I've had pretty good luck in not having things break down after an update until now. I downloaded the latest last night, and eversince, my airport just keeps on trying to 'connect'. It may connect, I'm not sure, but the top right icon keeps on scrolling 'connecting' until I either I reset the Airport or unplug/plug it back in. (I'm still using a modem connection.) I take the phone line and plug it into the internal modem jack and I can connnect again. I just can't use the Airport base! Anyone out there w/ problems after the last update?
